I assume I can copy MP3 files from my iMac to the SD Card in my DroidX. What should I name the folder that I put the files in? Can I put them is sub folders? How many levels down can I go? Or am I going in the wrong direction? Music storage is one area I am not very familiar with and I do not especially like iTunes anyway so I am easily confused by it. One other question regarding the DroidX and Music. I assume to hear anything earbuds must be connected or will it play thru the phone speakers?
